Hello,
two days ago I've upgraded to 1.2rc2 and the new sieve implementation
(version 0.1.4). Today I got the first mail that got stuck in the
postfix queue because deliver was dying with a segfault.
The mail is spam, thus I don't have any issues sharing it:
http://users.birkenwald.de/~berni/temp/deliver-segfault.mail
It happens with this small sieve script (my normal one is larger, but
this is the part that triggers the segfault):
http://users.birkenwald.de/~berni/temp/deliver-segfault.sieve
Note that I've been running this script unaltered for months, first with
Dovecot 1.1 and CMUSieve and now with various versions of Dovecot 1.2
and the new sieve implementation for about three weeks, this is the
first mail that got stuck.
I got a coredump, but without debugging symbols it doesn't tell that
much. If you can't reproduce it I'll compile it with debugging symbols
and try again.
